The DT207 Power Supply and RS-232 SimmStick, is simply a 1" SimmStick,
at the same price as other 1" SimmStick PCB's. It can be used as a
stand-alone Power Supply and/or a RS-232 Comms unit, or in conjunction
with a SimmStick Development system. The DT005 passive Motherboard is an
ideal candidate for this module.
